DESCRIPTION OF THE PREFERRED EMBODIMENT While the engine side shieldstructure of the present invention may be applied to vehicles havingvarious configurations, it is here applied to an articulated fourwheeldrive loader indicated in its entirety by the reference numeral 10. Theloader 10 includes front and rear sections 12 and 14, respectively,interconnected by a vertical pivot assembly 16, the front and rearsections respectively including front and rear frames 18 and 20supported on front and rear pairs of wheels 22 and 24.

A support arm structure 26 extends forwardly from and has its rear endpivotally connected to the front frame 18, as is conventional, forpermitting vertical movement of the arm structure 26. A bucket 28 ispivotally connected to the forward ends of the arm structure 26 in aconventional manner for permitting tilting movement of the bucket and apower-operated tilt linkage 30 is connected between the frame 18 and thebucket 28 for accomplishing tilting of the bucket.

Mounted on the rear vehicle section 14 just rearwardly of the frontsection 12 is an operator station 32 including a cab 34 in which islocated a seat 36 for supporting an operator so that he can operatevarious controls located within his reach, one such control being asteering wheel 38 located forwardly of the seat. Supported so as toextend outwardly from the right side of the rear frame 20 are aplurality of vertically spaced steps 40 which lead to a horizontalplatform 42 that extends alongside the cab 34 on a level even with thethreshold of a door 44 of the cab to thus provide a support structurefor an operator entering or leaving the cab 34.

A box-shaped reservoir 46 is mounted on the frame 20 just rearwardly ofthe cab 34 and includes a vertical rear wall 48 which bounds the forwardend of an engine compartment 50. A grill housing 52 is mounted on therear end of the frame 20 and bounds the rear end of the enginecompartment 50. The top and upper side portions of the enginecompartment 50 are bounded by a hood 54 which extends longitudinallybetween the reservoir 46 and the grill housing 52 and has its forwardand rearward ends respectively supported on flanges 56 and 58,respectively, that are integral with the reservoir wall 48 and the grillhousing 52. Forming part of the rear frame 20 andrespectively spacedvertically below the opposite sides of the hood 54 and bounding loweropposite side portions of the engine compartment 50 are right and leftlongitudinally extending channel members, only the right member beingshown at 60. The right and left channel members are disposed such thattheir respective upper and lower flanges extend inwardly towards eachother from respective outer planar surfaces, only the planar surface ofthe right channel member 60 being shown at 64. interconnecting the rightand left channel members and bounding the lower portion of the enginecompartment 50 is a bottom structure 68. A pair of rectangular openingsare delineated at the opposite sides of the engine compartment 50 byrespective lower edges of the opposite sides of the grill housing 52, bythe upper flanges of the right and left channel members 60 and 62, bythe reservoir 46 and by the grill housing 52, the respective openingsbeing closed by right and left engine side shield structures 70 and 72respectively supported by and extending vertically'above the right andleft channel members 60 and 62.

An engine 74 is supported on the rear frame 20 so as to be located inthe engine compartment 50. Located in the grill housing 52 and coupledto the engine 74 in a conventional manner for being driven by the engineis a blower-type fan 76 to the rear of which is located a radiator 78.It is to be understood that associated with the engine 74 and locatedwithin the compartment 50 are various elements requiring periodicservicing such as oil and fuel filters, various oil and fuel systemdrain or bleed screws and various engine cooling system drain cocks suchas those associated with the radiator and cylinder block.

Except for the fact that they are constructed so as to be respectivelyused on the right and left sides of the loader 10, the right and leftside shield structures 70 and 72 are identical. For the sake of brevity,only the right side shield structure assembly is described in detail.The engine shield structure 70 includes an access door and baffle platesupport structure comprising an angled base plate 80 extending along inoverlying relationship to the upper flange of the right channel member60 and is secured thereto through means of a plurality of vertical bolts82. Extending upwardly from and having lower ends secured in transverserelationship to the base plate 80 are a plurality of vertical supportplates, a first of the plates being indicated by the reference numeral84 and located adjacent the forward end of the side shield structure 70,a second of the plates being indicated by the reference numeral 86 andlocated adjacent the rear end of the side shield structure 70 and athird one of the plates being indicated by the reference numeral 88 andbeing in a location spaced a short distance forwardly from the rearsupport plate 86.

Extending longitudinally between the front and intermediate supportplates 84 and 86 and having its front and rear ends respectively securedthereto is an angled baffle plate 90 which is rectangular in side viewand has upper and lower edges 92 and 94 located equidistant from andlocated inwardly from a horizontal longitudinally extending bend line96. The upper portion of the side shield structure comprises avertically disposed longitudinally extending rectangular upper accessdoor 98 having a lower portion which overlaps an upper portion of thebaffle plate such that the upper baffle plate edge 92 is located behindthe access door 98, as viewed in FIG. 3. Three hinges 100 are secured tothe access door 98 at longitudinally spaced locations along the bottomthereof, the first and second ones of the hinges being located adjacentthe forward end and middle of the door and connected to a pair ofsupport brackets 102 which are in turn secured to the baffle plate 90while a third one of the hinges is located adjacent the rear end of theaccess door and is supported on a bracket 104 extending between andsecured to the rear and intermediate support plates 86 and 88. Thehinges 100 cooperate so as to define a horizontal longitudinallyextending pivot axis about which the access door 98 is swingable betweena closed position, as shown in the drawing, wherein it blocks access tothe engine compartment 50 and an open position wherein it is rotatedcounterclockwise, as viewed in FIG. 4, from its closed position.

For the purpose of releasably latching the upper access door 98 in itsclosed position, there is provided similarly constructed front and rearlatch structures 106 and 108. The latch structures 106 and 108respectively include latching elements in the form of latching rods 110and 112. The latching rod 110 includes a vertically extending centralportion 114 which is rotatably supported in upper and lower supportbrackets 116 and 118, respectively, fixed to the front support plate 84.The latching rod 110 further includes a transverse portion 120 whichinterconnects the upper end of the central portion 114 with a verticallyextending upper end portion 122 of the rod. Thus, it will be appreciatedthat, when the rod 110 is rotated about the longitudinal axis of thecentral portion 114, the upper end portion 122 will trace out an arcuatepath. As can best be seen in FIG. 7, the access door 98 has a horizontalbracket 124 integral therewith and provided with a latch elementreceiving receptable 126 shaped and located for receiving the upper endportion 122 of the latching rod 110 when the latching rod is in itslatched position as shown. As viewed in FIG. 7, the lower end of thelatching rod 110 is bent rearwardly and then outwardly to form a handle128 which may be grasped by the operator to rotate the latching rodbetween latched and unlatched positions.

The rear latching rod 112 is constructed and mounted similarly to theforward rod 110. Thus, the latching rod 112 includes a vertical centralportion 130 rotatably supported in upper and lower brackets 132 and 134,respectively, fixed to the rear support plate 86. The latching rod 112further includes a transverse portion 136 which joins the upper end ofthe central portion 130 with a vertically extending upper end portion138. A bracket 40 is secured to the inside of the access door 98 and isprovided with a receptacle (not shown) similar to the receptacle 126 andhaving the upper end portion 138 of the latching rod 112 located thereinwhen the latching rod is in a latched position as shown. A handle 142 isformed on the lower end of the latching rod 112 to provide means bywhich the rod may be manually turned.

A bottom portion of the engine side shield structure 70 comprises alower access door 144 which has a lower horizontal edge which extendsadjacent the base plate 80 and which has an upper edge which is locatedabove the lower edge 94 of the baffle plate 90 and extends parallelthereto between the front of the shield structure 70 and a location justforwardly of the intermediate support plate 88 at which location theupper edge is stepped vertically upwardly to a location just below thelower edge of the upper access door and from which the upper edge of thelower access door extends rearwardly to the end of the side shieldstructure 70. Three hinges 146 are secured at longitudinally spacedlocations along the lower portion of the access door 144 and areconnected to the base plate 80. The hinges 146 cooperate to define ahorizontal fore-andaft extending pivot axis about which the lower accessdoor 144 is swingable between a closed operative position, asillustrated, wherein the door prevents access to the engine compartment50 and an open position, as shown in dotted lines in FIG. 4, wherein thedoor is displaced 180 counterclockwise from its closed position andpermits access to the engine compartment.

Provided for the purpose of releasably latching the lower access door144 in its closed position are substantially identical front and rearlatch structures 148 and 150, respectively, which are located centrallybetween the front and intermediate vertical support plates 84 and 88. Ascan best be seen in FIGS. 3, 8 and 9, the front latch structure 148includes a horizontally disposed latching pin or rod 152 reciprocallymounted in front and rear vertically disposed ears of a mounting bracket154 which is secured to the inside of the access door 144. Whenthelatching pin 152 is in a latched condition as shown, the forward endof the pin 152 is located within an aperture or slot 156 located in thefront vertical support plate 84. For the purpose of biasing the latchingpin to its latched position, a coil compression spring 158 is receivedon the rod and has its rear end engaged with the rear ear of themounting bracket 154 and has its forward end engaged with a washer 160which is held in place by a cotter pin 162 extending through the pin152. Forward movement of the latching pin 152 is limited by a cotter pin164 which is disposed to engage the rear side of the mounting bracket154 when the latching pin is in its latched position. The rear latchstructure 150 includes a latching pin or rod 166 which extendsoppositely from the latching pin 152 and is mounted for horizontalreciprocable movement in front and rear vertically disposed ears of amounting bracket 168 secured to the inside of the lower access door 144.When the latching pin 166 is in a latched position as shown, therearward end of the pin is received in an aperture or slot 170 formed inthe intermediate vertical support plate 88. For the purpose of biasingthe pin 166 to its latched position, there is provided a coilcompression spring 172 which is received on the pin and has its oppositeends engaged with the forward ear of the bracket 168 and a washer 174held in place on the rod by a cotter pin 176. A second cotter pin 178 isprovided in the latching pin 166 at a location wherein it abuts theforward side of the mounting bracket 168 to thus limit the rearwardmovement of the latchingpin.

For preventing unauthorized entry into the engine compartment 50, asafety latch structure 180 is also provided for maintaining the loweraccess door in its closed position. The safety latch structure 180includes a strap-like latching element 182 which extends transverselyalongside an upper rearwardly facing portion of the intermediatevertical support plate 88, the latching element 182 being pivotallyconnected at an intermediate location thereof to the support plate 88through means of a horizontal longitudinally extending cap screw 184.The outer end portion of the latching element 182 extends through avertically elongated rectangularaperture 186 located in the access door144, the lower edge bounding the aperture being received in an upwardlyopening notch or receptacle 188 located along the underside of thelatching element 182. A security lock, shown here as a padlock 190,which may be of a well-known key-operated or combination type, isreleasably locked to an aperture provided in the outer end of thelatching element 182, the padlock 190 being too large to pass throughthe aperture 186 thus necessitating its removal before the latchingelement 182 can be disengaged from the door 144 to permit the latter tobe opened. The latching element 182 is biased to its latched positionthrough means of a coil tension spring 192 having one end connected tothe latching element 182 inwardly of the cap screw 184 and having itsother end connected to a bracket 194 which is cantilever-supported fromthe hinge support bracket 104.

in addition to preventing unauthorized access to the engine compartment50, the latch structure 180 prevents the door 144 from accidentallyfalling on the operator when the latching pins 152 and 166 are released.To carry out this operation, the notch 188 in the latching element 182is made sufficiently large so as to permit the door 144 to be tilted outfar enough to bring the latching pins 152 and 166 out of alignment withthe respective apertures 156 and 170 so that the operator may removeboth hands from the latching pins so that one hand can be used tooperate the latch element 182 while the other is positioned to supportthe door 144 when it is released.

Thus, it will be appreciated that when both the upper access door 98 andthe lower access door 144 are in their respective closed positions, thefront and rear latch structures 106 and 108 for releasably retaining theupper access door 98 in its closed position will be located entirelywithin the engine compartment 50 and will thus be inaccessible from theexterior of the compartment. Further, when the lower access door 144 isin its closed position, it is disposed closely adjacent the respectiveends of the handles 128 and 142 of the latching rods 110 and 112 so asto prevent the latch structures 106 and 108 from becoming accidentallyunlatched. This relationship of the access door 144 to the handles canbe best appreciated with reference to FIG. 7. Accordingly, once apadlock is installed in the latching element 182 of the safety latchstructure 180, unauthorized opening of the engine compartment isprevented.

An operator support structure is made as an integral part of the accessdoor 144 so as to be located for supporting an operator when he isperforming periodic servicing of components located within the enginecompartment when the access doors 98 and 144 are open. Thus, theoperator support structure includes a narrow elongate platform 196 whichis formed as an integral leg of the access door 144 and is disposed soas to extend horizontally above the base plate 80, when the access dooris in its closed position, between a location just rearwardly of theforemost of the hinges 146 and a location just forwardly of theintermediate vertical support plate 88. A plurality of gussets 198 aresecured between the platform 196 and the inner wall of the door 144 tothereby provide support for the platform. A horizontal step 200 issecured to the inside of the lower access door 144 at a location betweenthe rear and intermediate vertical support plates 86 and 88 and at alevel above the platform 196. A pair of supports 202 are welded to theinside of the access door 144 and are respectively secured to the frontand rear sides of the step to thus provide support therefor. As can bestbe seen in FIG. 4, when the lower access door 144 is moved to its dottedline open position, the normally outer planar surface of the access doorwill be in engagement with the outer planar surface 64 of the rightchannel member 60 and the platform 196 and step 200 will extendoutwardly from the channel member 60, the step 200 now being disposed ata level below that of the platform 196. As can be seen in FIG. 1, afurther step 204 is disposed so as to be located vertically below thestep 200 when the access door is open. An operator then wishing toservice components located within the engine compartment 50 would firststep on the step 204 and from there go to the step 200 and then onto theplatform 196 if desired. It is here to be noted that the steps 200 and204 are located so as to be rearwardly of the rear pair of wheels 24, soas to be easily accessible to an operator, and that the platform 196extends between the engine compartment 50 and the upper portion of theright wheel 24. Further, it is to be noted that by providing the upperand lower access doors 98 and 144, the movement of the access doors totheir respective open positions is in no way hindered by the rear pairof wheels 24.

The operation of the right side shield structure 70 is brieflysummarized as-follows. Assuming that the upper and lower access doors 98and 144 are in their closed positions as shown in FIGS. 3 and 4,unauthorized access to the engine compartment will be prevented sincethe padlock 190 will prevent the latching element 182 of the safetylatch structure 180 from being disengaged from the lower access door 144and with this door closed, the latching rods 110 and 112 cannot bemanipulated to release the upper access door 198. Further, the loweraccess door 144 will prevent any accidental movement of the latch rodhandle 128 and 140 in a direction for disengaging the respective upperend portions 110 and 112 from their respective receptacles.

Further, with the doors in their closed positions, both portions of thedoors 98 and 144 which overlap the baffle plate 90 will cooperate withthe baffle plate to define paths for the passage of air and sound waves.

Should the operator desire to perform service on any of the componentslocated within the engine compartment 50, he will first remove thepadlock 190 from the latching element 182. His next step will be tosimultaneously manipulate the horizontally arranged latching pins orrods 152 and 166 so as to respectively disengage them from the apertures156 and 170. The operator will then tilt the upper end of the loweraccess door 144 outwardly to the extent permitted by the notch 188 inthe lower side of the latching element 182. At this time the ends of thelatching pins 152 and 166 should be disposed out of alignment withrespective apertures 156 and 170 and the operator may then release thelatching pins. He will next raise up on the outer end of the latchingelement 182 to disengage it from the access door 144 and the latter willthen be swung to its open-line position as shown in FIG. 4. The step 200and the platform 196 will now be exposed and the operator may supporthimself thereon for subsequent steps of the operation. If it is requiredthat the upper access door 98 be swung to its open position in order forthe operator to perform the necessary service, he will grab one of thehandles of the latching rods 110 and 112 and pull on the same to causethe upper end of the rod to be disengaged from the associatedreceptacle. The operator will then similarly manipulate the otherlatching rod with one hand while having the other free to lower theaccess door 98.

Once the operator has performed the necessary service, the upper accessdoor 98 will first be returned to its closed position and the latchingrods 110 and 112 will be rotated to their respective latched positions.Next, the operator will grasp and retract the latching pins 152 and 166and simultaneously swing the lower access door 144 to its closedposition. Once the door is in place the pins are released and thesprings 158 and 172 act to latch them. The element 182 will now belocated in the aperture 186 and be engaged with the door 144. To securethe compartment 50, the padlock 190 is then installed.
